Recently, several approaches have achieved promising results by incorporating offline priors such as SD maps and HD maps or by fusing multi-modal data. However, these methods depend on stale offline maps and multi-modal sensor suites, resulting in avoidable computational overhead at inference. To address these limitations, we employ a knowledge distillation strategy to transfer knowledge from multimodal m","authors_text":"Aoyong Li, Bohan Li, Haiyang Yu, Han Jiang, Ruikai Li, Sijia Wen, Yilong Ren, Zhenning Li, Zhiyong Cui, Ziyang Yan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-08-21T15:37:18Z","title":"MapKD: Unlocking Prior Knowledge with Cross-Modal Distillation for Efficient Online HD Map Construction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2508.15653","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:7531bae09bf744812ec65f9bbff14f3c52a228540d7006c4a76a59db4ccc7298","target":"record","created_at":"2026-07-05T11:57:39Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"202c5076cb2e939b2284fd215549615d794564a4a86d88e34efd9ab93c8c9e75","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-08-21T15:37:18Z","title_canon_sha256":"2dfbd52361f66898b8a49411787b2bc5ede1ed1f3f245d9b43c34f864a4e0388"},"schema_version":"1.0","source":{"id":"2508.15653","kind":"arxiv","version":2}},"canonical_sha256":"527ff9cecd8563a658d7eaf51388c966d8d64364884890dcd3f05831c76074e7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"527ff9cecd8563a658d7eaf51388c966d8d64364884890dcd3f05831c76074e7","first_computed_at":"2026-07-05T11:57:39.519112Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:57:39.519112Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ypU0i/z9K7bVtXpJT7CJG2ctP6fGMGyqEl5GsT1QjaMEggiD+eA1jIXuXOddW2OoFlLGzHlSjhBj3jX6jGrdBA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:57:39.519662Z","signed_message":"canonical_sha256_bytes"},"source_id":"2508.15653","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7531bae09bf744812ec65f9bbff14f3c52a228540d7006c4a76a59db4ccc7298","sha256:5da0a8f166f6112b2c8c60c73453c84a229cdbb696405f1401003dcf4913bf9e"],"state_sha256":"245253e8c393d155f40c33e8d7c8c70edd72e92219a4218e5c7be0dce774bb9c"}
